Hence, these which are covered and deprived of this gas act on the sugar without deriving any vital benefit from the oxygen a circumstance which must tend to diminish the ratio of which we are speaking. This is the highest ratio we have been able to obtain.
If light be only a modification of heat, or a simple circumstance of its manifestation, or a component part of hydrogen, oxygen gas will be water deprived of its hydrogen, but combined with latent heat. This passage, so clear, so precise, and logical, is taken from a letter of Watt's, dated April 26, 1783.
"Why," he said slowly, "I don't just know the name of it, but it's that funny stuff you mix up sometimes to put in the oxygen tanks when we go up in the rarefied atmosphere in the balloon or airship." "Manganese and potash," spoke Tom. "That and two or three other things that form a chemical combination which goes off by itself of spontaneous combustion after a certain time.
The terrific heat from the first nozzle caused the metal to glow under the torch as if in an open-hearth furnace. From the second nozzle issued a stream of oxygen under which the hot metal of the door was completely consumed. The force of the blast as the compressed oxygen and acetylene were expelled carried a fine spray of the disintegrated metal visibly before it.
If we headed back to base in the Plumie ship with its Dirac pusher, we'd all be dead of old age before we'd gone halfway." "But unless we take it," raged Taine, "we hit this sun in fourteen days! We don't have to die now! We can land on the oxygen planet up ahead! We've only to kill these vermin and take their ship, and we'll live!" Diane's voice said dispassionately: "Report.
Now, let me take a piece of potassium, a substance which, even at common temperatures, can act upon carbonic acid, though not sufficiently for our present purpose, because it soon gets covered with a protecting coat; but if we warm it up to the burning point in air, as we have a fair right to do, and as we have done with phosphorus, you will see that it can burn in carbonic acid; and if it burns, it will burn by taking oxygen, so that you will see what is left behind.
He saw that the globe of earth was not more lawful and precise than was the supersensible; that a celestial geometry was in place there, as a logic of lines and angles here below; that the world was throughout mathematical; the proportions are constant of oxygen, azote, and lime; there is just so much water, and slate, and magnesia; not less are the proportions constant of moral elements.
At 30,000 feet the aeronauts were inhaling oxygen, and before reaching their highest point both had for a considerable time remained unconscious. In 1901 a new aeroplane flying machine began to attract attention, the invention of Herr Kress. A novel feature of the machine was a device to render it of avail for Arctic travel.
A given weight of air contains nearly 23.32 per cent of oxygen; hence to obtain 271.52 lbs. of oxygen, we must have about four times that quantity of atmospheric air, or more accurately, 1164 lbs. of air for the combustion of 100 lbs. of coal.
Oxygen has been proved to be indispensable, and hence we see a reason for the luminous organs in the glow-worm being so intimately connected, as above mentioned, with the air-tubes that ramify through the insect. This fact of itself might be taken as a strong indication of the chemical nature of the process to which phosphorescence is due.
